RAILWAY-CAR-TRUCK PEDESTAL AND JOURNAL-BOX.

Application led July 12, 1920.

T 0 all w hom t may concern Be it known that I, DANIEL IV. ALBER- MAN, acitizen of the United States, and a resident of the city of Chicago,inthe county of Cook and State of Illinois, have invented a new anduseful Improvement in Railway- Car-Truck Pedestals and Journal-Boxes, ofwhich the following is a full, clear, and exact description.

My invention relates to improvements in journal boxes and pedestals forrailway car trucks, and it consists in the combinations, constructions,and arrangements herein described and claimed.

An object of my invention is to` provide a journal box and pedestalhaving means for reducing the wearing of the one upon the other to aminimum.

A further object of my invention is to provide a journal box andpedestal of the type described, having larger bearing surfacescontacting each other than is ordinarily provided.

A further object of my invention is to provide a device of they typedescribed that is stronger and more durable than any heretoforeprovided.

Other objects and-advantages will appear in the following specification,and the novel features of the invention will be particularly pointed outin the appended claims.

My invention is illustrated in the accompanying drawings, forming partof this application, in which- Figure l shows the journal box andpedestal assembled on a truck,

Fig. 2 is a rear elevation of the journall box and pedestal,

Fig. 3 is a side elevation of the journal box and pedestal, and

Fig. 4 is a section taken along the line 4 4 of Fig. 2.

In carrying out my invention, I make use of a standard truck.having aframe 1, to which six of my pedestals 2 (one shown) are secured by bolts3. One of my journal boxes 4 is slidably disposed in a guideway 5 ineach of the pedestals 2. The pedestals 2, carrying the journal boxes 4,are located on each side of the frame 1, one in the center and one ateach end of the frame 1. A pedestal strap 6, secured to the frame 1 atone of its ends by the bolt 7, passes under the bottom of the threepedestals 2, and is secured at the other end of the frame 1 by a bolt(not shown).

Specification of Letters Patent.

disposed in the slots 8 Patented J an. 11, 1921. Serial No. 395,642.

Each pedestalA 2 has a slot 8 running through its'center, parallel withthe length of the frame 1. 4The slot 8 intersects the transverseguideway 5. An equalizing bar 9, situated between two of the pedestals2, is of both pedestals and rests on the tops of-the journal boxes' 4.The equalizing bars 9 are bent downwardly between the pedestals 2 andsupport the usual equalizing spring. A truck side bearing. 12 isconnected to each truck bolster 12 which bears on the elliptic spring11. The

I ouinal boxes 4 are carried by the axles 13 on which the wheels 14 aremounted. The parts thus far described are built in conforinitv with theusual practice and, with the exception of the pedestal 2 and the journalbox 4, form no part of my invention, except in so far as they coperatewith the journal box and pedestal.

, A description of one of my improved journal boxes and pedestals willsufiice, as all are precisely identical in construction.

The pedestal 2 has end portions 15 and 16 which are spaced from eachother by horizontally disposed bars 17 and 18. The bar 17 is spaced fromthe tops of the end portions 15 and 16, thus forming a groove 19 inwhich the frame 1 is adapted to be disposed. The bar 18 is* also spacedAfrom the bottoms of the end portions 15 and 16. The slot 8, parallelwith the end portions 15 and 16, is provided between the bars 17 and 18,and the end portions 15 and 16. The guideway 5, extending transverselythrough the pedestal 2, terminates at the under side of the bar 17. Apair of vertical outwardly extending vlugs 20 and 21, integral with theend portion 16, are spaced from and parallel with the outer edges of theguideway 5. A second pair of vertical outwardly extending lugs 22 and23, integral with the end portion 15, are spaced from and parallel withthe opposite edges of the guideway 5.

The journal box 4, horizontally disposed in the guideway 5, hasvertically extending recesses 24 and 25 in its opposite sides. Thelateral edges 26 and 27 of the two rencesses 24 and 25 respectivelyslidably engage the outer faces of the end portions 15 and 16. A pair ofvertically extending guides 28 and 29, integral with the journal box 4and disposed in the recess 24, are adapted to slidably engage the innerfaces of the end portions 15 and 16. A second pairl of verticallyextending guides 30 and 31, integral with the journal box 4 -anddisposed in the recess 25, are adapted to slidably engage the innerfaces of the end portions 15 and 16. A pair of vertical outwardlyextending lugs 32 and 33, adjacent to the edges 26 and 27 of therecesses 24 and 25 respectively are integral with the sides of thejournal box 4 and adapted to slidably engage the lugs 20 and 21 of thepedestal 2`. A second pair of vertical outwardly extending lugs 34 and35, adjacent to the opposite edges 26 and 27 of the recesses 24 and 25respectively, are integral with the sides of the journal box 4, andadapted to slidablly engage the lugs 22 and 23 of the pedesta 2.

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood. The passenger car isresiliently supported by the parts described. As the car moves over thetrack, the unevenness of the road bed is taken up by the verticalmovement of the pedestal 2 in the journal box 4. Due to the lurching ofthe car, caused by curves in the track, the journal box bears laterallyand longitudinally against the pedestal 2. The lateral movement of thejournal box against the pedestal 2 is limited by the guides 28, 29 and30, 31 bearing against the inner faces of the end portions 15 and 16 ofthe pedestal 2, and by the edges 26 and 27 of the recesses 24 and 25bearing against the outer faces of the end portions 15 and 16 of thepedestal 2. The longitudinal movement of the journal box 4 against thepedestal 2, formerly limited only by the sides of the guideway 5 of theend portions 15 and 16, is, in my device, limited also by the lugs 20,21 and 22, 23 of the outer faces of the end portions 15 and 16,contacting with the lugs 32, 33 and 34, 35 respectively of the journalbox 4. Thus the wear of the journal box 4 upon the pedestal 2 is reducedto a minimum, due to the large bearing surfaces contacting one another,and the life of both articles is prolonged.

It is obvious that many modifications and adaptations of the form of thedevice pictured in the accompanying drawings may be provided withoutdeparting from the spirit and scope of my invention.

I claim:

1. In a railway car truck, a pedestal, having a vertically extendingguideway therein, said pedestal being provided with pairs of oppositelyextending lateral lugs positioned adjacent the edges of said guideway,and a journal box slidably disposed in said guideway, said journal boxbeing provided with guide lugs abutting against said first named lugs,whereby lateral and longitudinal movement of said journal box in saidpedestal is reduced to a minimum.

2. In a railway car truck, a pedestal having a vertically extendingguideway intersected at its center by a transversely extending slot,said pedestal being formed with pairs of lateral lugs positionedadjacent the outer edges of said guideway, and a journal box slidablydisposed in said guideway, said journal box being provided with guidelugs extending within the intersecting slot for limiting lateralmovement of said j ournal box and with projecting guide lugs abuttingagainst the lugs provided on said pedestal, whereby longitudinalmovement of said journal box in said pedestal is reduced to a minimum.
